N.D. Cent. Code § 32-09.1-21
A plaintiff may obtain a two hundred seventy-day continuing lien on wages by garnishment. A plaintiff obtaining a continuing lien on wages by garnishment shall mark "continuing lien" on the caption of the garnishee summons. Each garnishment disclosure form must provide the garnishee will continue to hold the nonexempt portion of the defendant's earnings as the earnings accrue through the last payroll period ending on or before two hundred seventy days from the effective date of the garnishee summons, or until the sum held equals the amount stated in the garnishee summons, or until the employment relationship terminates, whichever first occurs.
If the garnishee's answers to a garnishment disclosure form provide the amount withheld is less than ten dollars, the garnishee is not required to return subsequent forms to the plaintiff until the amount withheld is ten dollars or more. For any pay period in which the garnishee is not required under this section to return the form to the plaintiff, the garnishee's answers from the previous form remain in effect. At the expected termination of the lien, the plaintiff shall mail the garnishee an additional copy of the garnishment disclosure form upon which the garnishee within ten days shall make further disclosure.
